Story

Introduction

This is a very basic project on Arduino. In this project I am going to show how we can automatic fade in and fade out the brightness of a LED by the help of Arduino UNO. Basically here we are going to control the brightness of a led light automatically.

Circuit Analysis

The circuit diagram of this project is very easy. Here we have just used a 5mm led, breadboard and Arduino UNO board. The anode of the led will connect with the Arduino digital pin 10 and the cathode will connect with the GND pin of Arduino.

int led = 10;
int brightness = 255;
int fadeAmount = 2;
void setup() {
 pinMode(led, OUTPUT);
 Serial.begin(9600);
}
void loop() {
 analogWrite(10, brightness);
 delay(10);
 brightness = brightness + fadeAmount;
 Serial.println(brightness);
 Serial.println(fadeAmount);
 if((brightness == 0) || (brightness == 255))
 {
   fadeAmount = -fadeAmount;
   Serial.println(fadeAmount);
 }
}
